To start a Killer Instinct crossover fanfiction, start small. Maybe focus on just one or two Killer Instinct characters in the new crossover setting at first. Create a vivid setting description for the crossover world. It could be a blend of the two universes' aesthetics. Then, start writing dialogues between the characters. Let their different personalities clash or cooperate, which will drive the story forward. As you write, keep in mind the rules and lore of both Killer Instinct and the crossover universe to make it believable.
First, decide which two or more universes you want to cross over. For example, if you choose Ultra Instinct from Dragon Ball and the world of Harry Potter. Then, think about how the Ultra Instinct power would work in the new universe. Would it be seen as magic? Next, create a plot. Maybe the character with Ultra Instinct has to save Hogwarts from a new dark threat. Start with a strong opening that introduces the character in the new setting.
When starting Killer Croc crossover fanfiction, you should first explore Killer Croc's personality traits. He's often seen as a brute, but he has his own set of emotions and motives. Then, choose a suitable crossover. Let's say it's a crossover with Wonder Woman. Consider how Killer Croc's more savage nature would contrast with Wonder Woman's grace and heroism. You can start by writing a short prologue that sets the stage for their encounter, perhaps a disturbance in the magical realm that draws both of them in, and then build the story from there.
Next, introduce the paradox. It could be something like the killer only kills those who are destined to live long, healthy lives. Explain how this strange rule came to be. Maybe it was a curse or a result of some strange experiment. This will set the stage for the rest of the story.
A cool Killer Instinct crossover fanfiction could involve a crossover with a superhero universe. Picture Jago with superpowers like Superman's strength or Spider - Man's agility. Or perhaps a crossover with the Mass Effect universe. The Killer Instinct characters could be part of a galactic battle against the Reapers, using their unique combat skills in a whole new setting.
You should also focus on character development. If you're crossing with the Fullmetal Alchemist world, consider how Chrollo would interact with the Elric brothers. He might see their search for the Philosopher's Stone as something he can use for his own purposes. Start with a small scene that sets the tone, like Chrollo arriving in Amestris and observing the alchemic practices there, and then build the story from that initial encounter.
First, decide which universe you want to crossover with Tracer. Then, research that universe thoroughly. For example, if it's a Star Wars crossover, know the rules of the Force, the different species, and the technology. After that, create a plot that involves Tracer being thrust into this new universe. Maybe she's chasing a villain through a wormhole that leads to the Star Wars galaxy. Start with an engaging opening scene, like Tracer suddenly appearing in the middle of a lightsaber duel.
First, decide which universes or characters you want to crossover with Gogeta. Then, think about the plot. It could start with a disruption in the Dragon Ball universe that leads Gogeta to another world. For example, if it's a crossover with the One Piece universe, it could be a mysterious energy that pulls Gogeta to the Grand Line.
First, decide which universe you want to cross Ichigo over with. Then, research the rules and characteristics of that universe. For example, if it's a crossover with the Star Wars universe, learn about the Force and the different species. Next, think about how Ichigo would fit into that world. What would his role be? After that, start with an interesting hook in your story, like Ichigo suddenly appearing in a strange new place.
First, decide which universe Gowther will cross over into. Then, think about how Gowther's character traits and powers will interact with the new world. For example, if it's a crossover with 'Naruto', Gowther's power to manipulate memories might be a big deal in a world where knowledge and hidden pasts are important. Just start with a simple scene, like Gowther arriving in the new world.
Begin with a hook. If it's a Sinbad and a historical fiction crossover, like with the Vikings. Start with a battle scene where Sinbad's ship is attacked by Vikings. This will immediately draw the reader in. Then, develop the relationship between Sinbad and the Viking characters. Show how they overcome their cultural differences and start to work together towards a common goal.
